Initial commit introducing the input subsystem into Zephyr. Includes the input_event data structure, the input_report_* APIs, an iterables sections based subscription API and two operation modes: synchronous, where the listeners are called directly, and asynchronous, where the listeners are called in a dedicated thread.
